Cons
Con GUI looks dated
Could use a new fresh user interface.

LZMA2 is unsafe and less efficient than the original LZMA. Use: 7Z LZMA Non-Solid, RAR 5 LZSS/PPMd Non-Solid, or ZIP Deflate. See here.
Con Does not support data recovery
It's not possible with 7-zip to add data recovery records to the archive which could repair minor integrity errors.

When you want to delete something, it will often highlight both a file and its folder. The whole folder is then removed if you don't de-select the folder manually.
Con Only the 32-bit version is free
You have to make a donation to be able to download the 64-bit version.
Con Cluttered and dated UI
The user interface has an outdated look, with a lot of button and menu options that can be overwhelming.
Con Unable to replace default file explorer
Con Buggy
Good facilities overall, but there's a bug that makes menus freeze and get stuck on the page.
